The Occult Tradition by David S. Katz is a book I read a few years ago and thoroughly enjoyed, mainly because it didn’t just discuss dubious claims of current witches dating back their ancestry to ancient Egypt, but took an in-depth look at ‘occult’ concepts in a very literal sense – in the sense of discussing hidden or obscure material.

A lot of the book focused on Jewish and Christian mysticism, which was interesting because again this isn’t something that’s always heavily discussed in books on occult themes.
